It runs four right-hand flutes in a long-reach configuration, allowing it to produce full thread profiles in a single helical pass. The cutting diameter is 0.3700 inches with a length of cut of 0.8880 inches and an overall length of 3.0000 inches. The shank diameter is 0.3750 inches. Built from submicron carbide grade with a bright\/uncoated finish, this tool is suited for precision thread milling on CNC machining centers where tap breakage is a concern or where thread size adjustability is required.\u003c\/p\u003e\n\u003cp\u003eThis thread mill is intended for internal threading applications producing 9\/16-32 UN threads in materials compatible with uncoated solid carbide tooling. The long-reach design accommodates deeper bores or features with limited radial clearance. Typical applications include precision machined components in aerospace, hydraulic, and instrumentation work where thread form accuracy and surface finish are critical. Coolant-through is not available on this tool, so external coolant or mist systems should be used to manage chip evacuation and heat during the cut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFour right-hand helical flutes for smooth chip flow in internal thread milling\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade provides wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eLong-reach design allows threading in deeper bores with limited clearance\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eCuts 9\/16-32 UN internal threads to standard thread form in a single helical interpolation pass\u003c\/li\u003e\n  \u003cli\u003eMinimum nominal diameter of 0.5625 inches establishes the smallest bore this tool will thread\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers capable of helical interpolation to produce 9\/16-32 UN internal threads. Compatible with standard 3\/8-inch tool holders, collet chucks, and shrink-fit systems. Refer to the machine tool manufacturer and cutting data recommendations for feeds, speeds, and radial stepover values appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThread mills must be run on a CNC machining center with helical interpolation capability  -  this tool cannot be used in a manual drill press or tapping head. Secure the 0.3750-inch shank in a balanced, low-runout holder to maintain thread accuracy and tool life. Power down the spindle and confirm the tool is fully seated before tightening the holder. Use external flood coolant or mist to clear chips from the bore during the cut, as this tool does not have coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch\u003c\/strong\u003e: 32 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.3700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Nominal Diameter\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.8880 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Mill Type\u003c\/strong\u003e: Long Reach\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242117\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TMI370-32H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52097608220978,"sku":"TMI370-32H","price":228.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf0502d2047f746bade6e64bf2b972dc_debd80ee-5c4d-4601-b177-e9fecfea629c.jpg?v=1790067061","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-tmi370-32h-thread-mill-9-16-32","provider":"Voomi Supply","version":"1.0","type":"link"}
